I have currently connected three sharp ir GP2Y0A21YK sensors, one servo and one motor controller.

With just one sharp ir sensor connected, everything works well. But when I connect two or more, the axon just starts restarting at pretty short intervals (varies from 1 to 5 seconds, mostly).

I've tried one 1500 MAh 7.2 volts battery, one 2500 MAh 7.2 volts battery and Ive tried a pretty good voltage supplier. I've tried the batteries parallell-coupled. The axon just keeps on resetting with two or more sharp ir sensors connected. What could be the problem? Im currently using 1.01 of the axon source code, I will upgrade to 1.05 within the day. But I couldnt see why this would do this?

Any batteries recommended for my use? Perhaps a battery just for the sharp irs would be good?

Solution: Hook up a small condensator to the + and - poles of the sharp connector. I used a 22 uF condensator, worked great. Totally stable now And the results from the axon is much better now, finally getting good readings.
